State-run Ghana National Petroleum Corporation (GNPC) is still interested in acquiring Kosmos Energy's stake in the Jubilee oil field, a source within the company told Reuters on Thursday.

We are still pursuing that and we are very hopeful of reaching an agreement (with Kosmos), the GNPC source said on condition of anonymity.

Sources earlier in the week told Reuters that Exxon Mobil had reached a multi-billion-dollar agreement with Kosmos to buy the stake in the Jubilee field, one of the largest oil finds in West Africa in the past decade.
